It exists a difference in English that I do not find any equivalent (for now) in French: the difference between “accurate” and “precise”. Even if usually we use one or the other to tell the same thing, in fact, there is a slight difference that take a real sense according to the context.
To show that difference, I take an example in a vision lecture that I had recently.
Figure a. shows a precise and accurate distribution of the dots. Figure b. shows a precise but no accurate distribution. Figure c. accurate but not precised distribution. And finally, figure d. shows an inaccurate and imprecise distribution.
- accurate: the average distribution is centered in zero.
- precise: the distribution is colocalized around or on the same point.
